Abstract
Live-bearing (viviparity) has evolved from egg-laying (oviparity) many times in vertebrates. The life history consequences of being one or the other parity mode are well recognised but the genetic basis was previously uncharacterised and therefore its evolutionary generality not known. In my talk I will share some recent results on the genetics and phenotypes of the youngest known example of parity mode switch in an amniote – Europe’s common lizard. This includes new evidence for the functional genes of key reproductive traits for oviparity or viviparity, signals of evolution and selection at shallow time scales, and sharing across vertebrates at deep evolutionary time scales. I will also explore the evidence for a possible reversal back to oviparity in the same species, ie breaking Dollo’s Law.
